WJ Rear Axle Swap

I did a seach and cannot find anything about this. I have a 2000 WJ with the Dana 35C rear axle. I want to swap in a stronger rear axle, I was thinking about a ford 8.8. But i was told by a 4x4 shop and Clayton Off Road Mfg said the WMS on a Wj is wider than a ZJ. I know if you put a ford 8.8 into a ZJ you need 3/4" spacers on each side. I also know that the ZJ is a 5x4.5" and a WJ is a 5x5" lug pattern and the Dana 35C is 57" from backing plate to backing plate. What options do I have besides calling Dynatrac and spending $4000 for a new axle.

Thanks for the help.

Army man,

Over on JeepsUnlimited I believe Puma was the one who did an 8.8 swap just yesterday. Their server is down right now but I'll get you that link as soon as I come across it. He got the 8.8 of a wrecked Merc Mountaineer from the boneyard and seemed to go very well. Probably about 800 bucks in total.

I beleive you can get a D44a from a Limited/laredo with Quadra drive, (tow package if you want 3.73s) you will get a slightly stronger axle and a LS, and it shouldn't cost you 4K, and you don't have to worry about your bolt pattern.

Anything else will require significant mods to fit, since WJ's have the center upper link on the pumpkin.

Yep the Super 35 would work very well.

IIRC, that's what Hunter's running.

dont bother with the super 35 kit. they're plenty good for TJ's and lighter rigs but not so much on our ZJ's/WJ's.

If you want somethin beefy find a 9" out of an older ford truck and build it up to put under your WJ. They can be found w/ the 5.5 bolt pattern so that wont be a problem. I know ur in NC also so if you need any help or advice just shoot me an IM on Puma297 or private message.

I am thinking about doing a 9 inch swap, only thing is the driveshaft has to come off to change the fluid.

No clue but you can get ANYTHING for a ford 9 inch, they are used a lot in street rods and race cars, between them and quick changes thats all you see.

Are you saying that the driveshaft having to be removed in order to change the fluid is effecting whether or not you will do the swap?

Any clue what the WMS is for the 9"? I was told that the WJ's wms is 63.5".
